Gear rack machining apparatus

Abstract

The invention relates to a rack processing equipment, which comprises a machine bed, a worktable arranged on the machine bed, and a rack processing machine which is slidably arranged on the machine bed in the X-axis direction and is close to the worktable. head, the workbench is cylindrical, and it is rotatably arranged on the machine bed around its own axis, the axis of the cylindrical workbench extends along the X-axis direction, and the workbench A plurality of mounting grooves for mounting the rack and extending along the X-axis direction are provided on the outer peripheral wall of the workbench, and the multiple mounting grooves are distributed along the circumferential direction of the workbench; due to the use of a cylindrical workpiece On a workpiece table, multiple rack blanks can be installed along the installation groove on the outer peripheral wall, so that by turning the table, multiple gear blanks can be processed at the same time, which not only improves the processing efficiency, but also reduces the cost of one-time processing. The error of multiple root racks is small, which improves the machining accuracy.

Description

technical field [0001] The invention relates to a gear rack processing equipment. Background technique [0002] In the prior art, the processing method of the rack uses milling cutters of different standards to directly grind the raw materials. For the rack with small modulus, this processing is relatively simple and convenient; but when the modulus of the rack increases , it is not suitable to use the milling cutter to directly grind into teeth, so people usually plan the rack blank by planing with a planer, but because the entire tooth shape needs to be planed out, the amount of planing will become very large Large, and the time required for processing will become very long at the same time. Whether using a milling cutter to process a small-modulus rack or a planer to process a large-modulus rack, in the process of processing, each rack blank will be processed one by one. Processing, its processing efficiency is very low. Contents of the invention [0003] The object o...

[0002] In the prior art, the processing method of the rack uses milling cutters of different standards to directly grind the raw materials. For the rack with small modulus, this processing is relatively simple and convenient; but when the modulus of the rack increases , it is not suitable to use the milling cutter to directly grind into teeth, so people usually use a planer to plan the rack blank by planing, but because the entire tooth shape needs to be planed, the amount of planing will become very large Large, and the time required for processing will become very long at the same time. Whether using a milling cutter to process a small-modulus rack or a planer to process a large-modulus rack, in the process of processing, it is a single rack blank one by one. processing, its processing efficiency is very low
